    Abstract: Method and apparatus for managing a memory, such as but not limited to a flash memory. In accordance with some embodiments, initial state information is stored which identifies an actual state of a garbage collection unit (GCU) of a memory during a normal operational mode. During a restoration mode after a memory power cycle event, a virtualized state of the GCU is determined responsive to the initial state information and to data read from the GCU. The memory is transitioned from the restoration mode to the normal operational mode once the virtualized state for the GCU is determined.

    Abstract: Apparatus and method for object storage, such as a solid-state drive (SSD) or array thereof. In some embodiments, data arranged as an object are presented for storage to a non-volatile memory (NVM) of a data storage device. Prior to storage, a configuration of the NVM is adaptively adjusted, such as by adjusting a garbage collection unit (GCU) layout, an error correction code (ECC) scheme, and/or a map metadata format used by the NVM. The object is thereafter stored to the NVM using the adaptively adjusted configuration. A controller of the data storage device generates a predicted remaining storage capacity of the NVM in terms of additional objects that can be stored by the NVM responsive to the adaptively adjusted configuration of the NVM. A non-linear sliding scale may be used such that a greater number of smaller objects or a smaller number of larger objects may be accommodated.

    Abstract: Apparatus and method for managing metadata in a data storage device such as a solid-state drive (SSD). The metadata are stored in combined (combo) pages in a non-volatile memory (NVM) each having first and second level map entries. The second level map entries provide a logical-to-physical address translation layer for user data blocks stored to the NVM, and the first level map entries describe the second level map entries in the combo page. A global map structure is accessed to identify a selected combo page in the NVM associated with a pending access command. The first and second level map entries are retrieved from the combo page, and the second level map entries are used to identify a target location for the transfer of user data blocks to or from the NVM.

    Abstract: Method and apparatus for enhancing performance of a storage device, such as a solid-state drive (SSD). In some embodiments, the storage device monitors a rate at which client I/O access commands are received from a client to transfer data with a non-volatile memory (NVM) of the storage device. A ratio of background access commands to the client I/O access commands is adjusted to maintain completion rates of the client I/O access commands at a predetermined level. The background access commands transfer data internally with the NVM to prepare the storage device to service the client I/O access commands, and can include internal reads and writes to carry out garbage collection and metadata map updates. The ratio may be adjusted by identifying a workload type subjected to the storage device by the client.

    Abstract: Systems and methods presented herein provide a controller is operable to increase a number of suspend operations during read Input/Output (I/O) operations of a storage device, and to detect an increase in response times for write commands due to the increased number of suspend operations. The controller is also operable to decrease the number of the suspend operations during the reads of the storage device to decrease the response times of the write commands.

    Abstract: A data storage system may have a number of data storage devices that each have a non-volatile memory connected to a memory buffer. The memory buffer can consist of a map unit having a predetermined size. In receipt of a data sector into the map unit of the memory buffer, the data sector may be identified as a runt with a runt module connected to the memory buffer and the non-volatile memory. The runt module can generate and subsequently execute a runt handling plan to fill the size of the map unit before storing the filled map unit in the non-volatile memory.

    Abstract: A storage compute device includes a data storage section that facilitates persistently storing host data as data objects. The storage compute device also includes two or more compute sections that perform computations on the data objects. A controller monitors resource collisions affecting a first of the compute sections. The controller creates a copy of at least one of the data objects to be processed in parallel at a second of the compute sections in response to the resource collisions.
